Short
TE (15ms) Spectroscopic Imaging of the Human Brain at 7T Using Transceiver
Arrays and B1 Shimming Based Localization

The presence of ultra high field systems (7T) dating
from late 1990s, there have been few reports of their use in spectroscopic
imaging (SI) studies. This limitation is due to the inherent disadvantages of
high field which result in a 5-12 fold increase in power deposition at 7T in
comparison to 3T. These problems become especially severe when inplane volume
localization is used for SI. To overcome these limitations we have developed a
short TE (15ms) SI sequence utilizing an 8 element 7T transceiver array and a
B1 shimming based method for in-plane localization.
